SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent N o. 533,578, dated February 5, 1895.

Application filed J' une 29, 1894. Serial No. 616,040- (No model.)

To @ZZ whom it may concern:

Be it known that I, HERMAN BOKELMANN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sheet-Metal Cans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specilication.

My invention relates to improvements in sheet metal cans, and has for its primary object to provide a can for the carrying of liquids, such as milk and the like.

A further purpose of the invention is to provide a lid or cover hinged to the side of the can, and fastened down by means of a suitable clamping device, when desired.

Furthermore, the invention has for another object, the arrangement of a pump to be used in connection with the can, whereby the liquid can be drawn from the interior of the can without removing the cover.

Figure lis a vertical section of the can, comprising therein the several novel features of construction and arrangement of parts embodying the principles of my invention. Fig. 2 is a plan view of the can and cover. Fig. 3 is a detail sectional view of part of the cover and a locking bolt connected therewith.

Fig. 4 is a side view of y one of the clamps; and- Fig. 5 is a detail section of theclamp-boltand a hand wheel connected therewith, for tightly forcing the clamp down upon the cover of the can. Fig. 6 is a vertical section of the can, in which the liquid pump has been dispensed with.

Similar letters of reference are employed in said above described views to indicate corresponding parts.

The invention consists in the novel form of sheet metal can herein shown, as a new article of manufacture, and further, in certain details of construction and combinations of parts, as will beybereinafter more fully described and linally embodied in the clauses of the claim.

In said drawings A represents a metal can of any desired form and size, made of sheet metal, and provided onoppositc sides of the neck c1. with suitable lugs or ears o. and o?, substantially as shown in Figs. l, A and 5.

As will be seen more especially from Fig. 5, the upper ear a is provided with a hole a3 having a smooth bore, while in the lower ear 0.2 is a hle ai. A clamp-bolt b is passed through said hole o3 in the ear ce and through the hole (1,4 in the ear d2, and rotatively arranged on a screw-thread on said bolt, between said ears, is a suitable hand wheel c.

As will be seen from Figs. 1 and G, the bolt b to the left of the drawings is provided with a hook-shaped clamping rod b pivotallyconnected at b2 with said bolt ZJ, while the bolt b3, at the right of the drawings, is provided with an arm b4 having pintle-bearing ears b5, between which is pivotally arranged an ear cl of the cover or lid d, said parts being held together by means of a suitable pin d2. Said cover is preferably provided on its under side with an annular projection or bead d3, which, when the lid is closed, fits snugly iu a correspondingly arranged groove o5 in the surrounding rim c. of the neck of the can, as will be clearly seen from Fig. 3. lfVhen said lid or cover is closed and it is desired to firmly clamp the cover down to prevent the same from being opened by accident, and thereby spilling the contents of the can, all that is necessary, is to turn the hand wheels c on said bolts b and b5, whereby the hook-shaped end of the clamping rod b' and the arm b4 cause said lid or cover to be tightly brought down upon the surrounding edge of the neck of the can to seal the same. Saidlid or cover d is preferably provided with suitable guides e and e in which slides alock-bolt c2, as shown in Fig. 3. The hook-end of the clamping rod can be arranged in a depression di formed in the top of the lid d, and the free end h6 of the hook on said rod b is dattened, as shown, to bring it flush with the upper surface of the lid. When the lid has been fastened down, as above stated, the bolt e2 is pushed forward, thereby bringing its free end e3 directly above said end h6 of the clamping hook on said rod b. At the same time, the end e4 of a screwthreaded stud e5 is brought directly above the depression d5 in the lid and by screwing the lower end of said stud into said depression, the bolt e is ilnniovably held in its locked po- IOO sitiony above the hook-end of the clamping rod b, as will be clearly understood from an inspection of Fig. 3. Said lid dy may also be provided with a central opening d6 above which is a pivotally arranged plate C17 provided with a screw-stud de, similar iny construction to the stud e5, whereby said plate or disk dT can be turned over said opening d6 in the lid and firmly held in its closed position by said screw-stud, as will be understood. Said disk kor plate CZ7 is not absolutely essential, but it isfof great use to remove the liquid in the can, Without disturbing the clamping devices connected with the can and the opposite edges of the lid d.

The .can may kbe provided with any suitable form of lift pump for drawing the liquid fromY the can. The pu-mp illustrated in the present case, consists essentially of a cylinder f arranged in a recess a7 in the bottom of the can. Said cylinder is open at the bottom, be ing preferably provided with inletholes f and asuitable valve f2 through which the liquid passes into thechamber directly beneath the piston g ony the tubular piston rod g. Said rod g is connected at the top with a removable tube g3 Vhaving anv outlet g2 Vanda handle g4.

From Fig. 1, it will be seen, that when the pistonrodV is operated, the valve f2 and the valve g5, will open and close, respectivelygto permit the liquid in the can to be forced into the tubular piston rod and thence from'its outlet g2. The upper portion of said rod may be removed at will, to permit the closing of the plate or disk di, or to permit the swinging open of said lid or cover d, when neces sary. Said piston rod g may be provided with teeth or serrations 'h on the one side of said tube, and loosely arranged to slide on said rod g and on suitable guide rods t' and z" is a sheet metal float 7' provided with a catch j', substantially as shown in said Fig. l. Said iioat, will always Iioat upon the surface of the liquid in the can, with the said catch j in holding contact with one of the teeth h on said rod g. When the said rod g is pushed down, the catch j will force the float beneath the surface of the liquid, thereby thoroughly stirring or mixing the liquid, While the pump is being operated. As soon as the rod g moves upwardly, the float j will of its own accord float to the surface of the liquid, but when the rod g is again pushedA down, the catch j will also force the iioat beneath the surface of the liquid.

It will be observed that cans constructed in accordance with my invention are strong and bearing arm arranged in said ears on one side of the can, a lid or cover hinged to said pintle-bearing arm, a clamp-bolt in said ears on the opposite side of the can, adapted to be clamped down over the edge of the lid when closed, and hand wheels c on said bolts, substantially as and for the purposes set forth.
